Abstract
A lock nut to be threaded onto a threaded shank which has a keyway. The lock nut has a base, a key on the base to fit in the keyway, a peripheral wall with axial angularity spaced apart recesses, and a wave spring. The wave spring has ridges and radial tabs to fit in the recesses. An internally threaded nut has radially-extending grooves complementary to the ridges to hold the nut against rotation relative to the wave spring when the ridges fit in the grooves. The tabs can be contacted by a drive member to compress the wave spring and remove the ridges from the grooves to enable the nut to turn during installation and removal.
